Question

Given sequence below, write and explicit arithmetic formula using the variable “n” to represent the sequence

-4, -9, -14, -19

Answer 1

Answer:

a_(n)= -4-5(n-1)

Step-by-step explanation:

a_{n}=a_{1}+(n-1)d

a_n = the nᵗʰ term in the sequence

a_1 = the first term in the sequence

d = the common difference between terms
